Rule for future years (POSIX TZ string)
CET-1
The standard time is called CET and is UTC+1. POSIX writes the offset with the opposite sign (west of Greenwich is positive), which is why the string says "-1". There is no daylight saving rule: the zone stays on this offset for every year after the end of its explicit transitions. Software that has no full tzdata copy, such as many embedded devices, can use this string directly as the TZ environment variable.
